Kwiziko ledatha, iimodyuli ze-optical zikhona kuyo yonke indawo, kodwa zimbalwa zithetha ngazo.Enyanisweni, iimodyuli ze-optical sele ziyimveliso esetyenziswa kakhulu kwiziko leenkcukacha. ngoko ngaphandle kweemodyuli ze-optical, amaziko edatha awakwazi ukusebenza konke konke.Imodyuli ye-optical iguqula isignali yombane ibe ngumqondiso we-optical kwisiphelo sokudlulisa ngokuguqulwa kwe-photoelectric, kwaye emva koko idlulisele isignali ye-optical kwisignali yombane ekupheleni kokufumana emva kokudluliselwa. ngokusebenzisa i-fiber optical, oko kukuthi, nayiphi na imodyuli ye-optical inamalungu amabini okudlulisa kunye nokufumana.Umsebenzi, yenza ukuguqulwa kwe-photoelectric kunye nokuguqulwa kwe-electro-optical, ukwenzela ukuba iimodyuli ze-optical ziyakwazi ukwahlula kwizixhobo kuzo zombini iziphelo zenethiwekhi.Kukho amawaka ezixhobo kwiziko ledatha ephakathi, kwaye kuthatha ubuncinane iimodyuli ze-optical optical. ukufezekisa uxhulumaniso olupheleleyo lwezi zixhobo.Nangona ixabiso lemodyuli enye ye-optical aliphezulu, likhulu kakhulu.Ngale ndlela, ixabiso elipheleleyo leemodyuli zokuthengwa kwedatha yeziko ledatha aliphantsi, kwaye ngamanye amaxesha lide ligqithise ixabiso lokuthenga. izixhobo zenethiwekhi ngokubanzi, zibe yinxalenye yemarike kwiziko ledatha.
Imodyuli ye-optical incinci ngobukhulu, kodwa umphumo wayo awuncinci.Ayinakudlalwa ngaphandle kweyiphi na isikhungo sedatha.Ngokwandiswa okuqhubekayo kwemakethe yedatha yedatha, imarike yemodyuli ye-optical iqhutywe ngokuthe ngqo.Kwiminyaka emihlanu edlulileyo, imakethi yemodyuli yehlabathi jikelele ikhule ngokukhawuleza.Kwangoko ngo-2010, ingeniso yentengiso yemodyuli yehlabathi jikelele yayiyi-2.8 yeebhiliyoni zeedola zaseMelika.Ngo-2014, imarike yemodyuli yehlabathi jikelele idlule kwi-US $ 4.1 yezigidigidi, kwaye imarike yemodyuli ye-optical kulindeleke ukuba ithengiswe ngo-2019. Ingeniso iya kunyuka ukuya kwi-6.6 yezigidigidi zeedola. umthamo omkhulu.Kuqikelelwa ukuba ngo-2017, ingeniso yemodyuli ye-10G / 40G / 100G yehlabathi jikelele iya kufikelela kwi-3.1 yeebhiliyoni zeedola zase-US, kwaye i-market ye-module optical iyonke iya kuphendula ngaphezu kwe-55%. kunye ne-100G iimodyuli ze-optical ziya kuba ziphakamileyo kwi-17% kunye ne-36% ngokulandelanayo, kwaye imfuno enkulu yeemarike ibangele abaninzi abavelisi ukuba batyale imali kubo.Kwakhona ukubona inzuzo enkulu ye-market module optical, abantu abaninzi bathatha ingozi kwaye benze ishishini. njengeemodyuli zomgunyathi.Umzekelo, iimodyuli zamehlo zithengwa ngokuthe ngqo kubavelisi bemodyuli ye-optical kwaye emva koko zithengiswa kwabanye abathengisi okanye abathengi beziko ledatha.Kukwakho ezinye iimodyuli ezizenza ngathi zingabenzi bemodyuli ye-optical rhoqo, i-shoddy, kunye nokutshintshiselana kwamaxabiso aphezulu kwinzuzo ephantsi. Imodyuli yokukhanya ephantsi isetyenzisiweyo, umngcipheko unokuza nangaliphi na ixesha.Ezinye iimodyuli eziphantsi ze-optical zivelisa ukushisa okukhulu, ezinye iimodyuli ze-optical zineephakheji ezininzi ezingalunganga, ezinye iimodyuli ze-optical aziqinisekanga, ezinye iimodyuli ze-optical zineerekhodi zolwazi lwangaphakathi, njl. Sele kukho iimodyuli ezininzi ezisezantsi ze-optical kwiimarike, eziye zaphazamisa le marike..Nangona kunjalo, oku kubonisa kwakhona ukuba i-market module ye-optical market ishushu.Enyanisweni, ukuvula ngaphakathi kwimodyuli ye-optical, unokubona ukuba isakhiwo silula, kwaye asibandakanyi iisekethe eziyinkimbinkimbi.Ingongoma kuphela kukuba inkqubo yokuvelisa iphezulu kakhulu, kwaye imveliso yenkqubo ehluphekileyo iya kuchaphazela kakhulu umgangatho we-optical path, enokuthi ihambelane nokukhanya kwesiphelo esichaseneyo.Iimodyuli azikwazi ukukhutshwa, okanye ezinye iimpazamo zekhonkco zihlala ziveliswa, ezichaphazela ukuhanjiswa kwedatha.Ingakumbi namhlanje, iimodyuli ze-high-speed optical ezifana ne-40G kunye ne-100G zihlala zifuna iimfuno ezingakumbi kwinkqubo yokuvelisa iimodyuli ze-optical, ukwenzela ukuba kungabikho bonke abavelisi beemodyuli ze-optical. inokuvelisa iimodyuli ezinjalo ze-100G, ezenza kwakhona iimodyuli ze-100G ezibonakalayo.Amaxabiso ahlala kwinqanaba eliphezulu.Imodyuli ye-optical ngokwenene iyimveliso eneemfuno eziphezulu zobugcisa.Umxholo wobugcisa uphezulu.Iindleko zemodyuli ye-optical ngokwayo ayiphezulu, kodwa ixabiso elongezelelweyo lobuchwepheshe liphezulu.Ngenxa yokuba imodyuli ye-optical kufuneka iphuhliswe, i-optical, iteknoloji yesekethe kunye nenethiwekhi zihlala zifuneka.Abaphandi kwiinkalo ezahlukeneyo kufuneka batyale imali eninzi yophando lwesayensi.Igalelo labasebenzi kule ndawo likhulu, kwaye kufuneka libalwe kwiindleko zokwenza iimodyuli ze-optical.Oku kugcina ixabiso leemodyuli ze-optical kwizinga eliphezulu.Ngokuqinisekileyo, xa kuthelekiswa namaseva kunye nezixhobo zenethiwekhi, inzuzo yeemodyuli ze-optical ziphezulu nakakhulu.Ngokungafaniyo namacandelo emarike afana neseva, inethiwekhi kunye nokugcinwa, ukhuphiswano kumacandelo emakethe ye-optical lwanele.Ukhuphiswano kwimarike yemodyuli ye-optical ixutywe.Abavelisi abaninzi bemodyuli ye-optical yangaphandle bahlala kwimarike.Ubume babathengisi abaqhelekileyo, abavelisi abaninzi basekhaya bemodyuli banokufumana intengiso eninzi, ngokubanzi, abavelisi bemodyuli ye-optical babengcono kakhulu kwiminyaka yakutshanje.Ngokukodwa ngokunyuka kweemfuno ze-40G / 100G iimodyuli ze-optical kwiziko ledatha, imarike izise amathuba aneleyo kubakhiqizi bemodyuli ye-optical, kwaye ezi modyuli ezikhawulezayo zineenzuzo eziphezulu.
Akulula ukubonelela ngeemodyuli ze-optical ezithembekileyo kwaye zihlangabezana neemfuno zokusetyenziswa kweziko ledatha.Kwiminyaka embalwa edlulileyo, obunye ubuchwephesha kwiziko ledatha luye lwaphuculwa ngokuqhubekayo, kwaye iimfuno zeemodyuli ze-optical nazo zanda.Eyokuqala kukuba ukuba izinga liphezulu.Okwangoku, i-interface yomncedisi isuka kwi-1G ukuya kwi-10G, kwaye i-aggregation switch ivela kwi-10G ukuya kwi-40G / 100G.Imigangatho ye-25G kunye ne-400G nayo iyaqulunqwa.Nje ukuba umgangatho usenziwe, uyilo oluthile lwemodyuli yokukhanya kunye nophuhliso luya kuqalisa.Iza kuphucula ngakumbi ubunakho be-bandwidth yenethiwekhi yeziko ledatha.Eyesibini kukuba ibe luhlaza kwaye iphantsi kokusetyenziswa kwamandla.Ukusetyenziswa kwamandla kwiziko ledatha kukhulu kakhulu, kwaye ukusetyenziswa kwamandla okubala ubushushu kuyinkunkuma enkulu.Ukuba ukusetyenziswa kwamandla okusebenza kwemodyuli ye-10G ye-optical yi-3W, ngoko ukusetyenziswa kwamandla kwebhodi yokutshintsha kwe-48 yezigidi-megabit kuya kufikelela kuphela kwimodyuli ye-optical.I-144W, ukuba ifowuni yenethiwekhi eneebhodi ze-16 ifakiwe, iya kubaI-2300W, elingana ne-bulb ye-23 100W ngexesha elifanayo, elinamandla kakhulu.Eyesithathu kukuba noxinzelelo oluphezulu kunye nokugcina indawo.Nangona isantya semodyuli ye-optical sinyuka kwaye siphezulu, sinokuyilwa ukuba ibe yincinci kwaye incinci.Imodyuli yangaphambili ye-GBIC ye-optical module inezinga le-Gigabit kuphela, kwaye intloko inkulu kune-10G yangoku.I-100G yangaphambili ye-module optical port yayiphantse ibe yi-10CM ubude, kwaye ngoku imodyuli ye-100G ye-optical kunye nobukhulu be-10G ayifani.48 100G i-port densities can makwenziwe kwibhodi enye.Okwesine yindleko ephantsi, kwaye ixabiso eliphezulu leemodyuli ze-optical ze-100G liye lacinezela ezinye iimfuno zemarike kwinqanaba elithile.Amaziko amaninzi edatha adimazekile kwixabiso eliphezulu le-100G iimodyuli ze-optical.Ngenxa yokuba kungekhona kuphela imodyuli ye-optical, kodwa kunye nesixhobo esixhotywe ngayo, kufuneka iphinde itshalwe, ukuze ingabi yindleko encinci.Ukuba imodyuli ye-100G ye-optical module. ingancitshiswa kakhulu kwiindleko, ngokukhawuleza iya kuba yinto eyaziwayo kwiziko ledatha.Okwangoku, isikhungo sedatha esikwaziyo ukuhambisa i-100G i-interconnection ayinqabile.Ngoko ke, akuwona umsebenzi olula ukubonelela ngeemodyuli eziphezulu ze-optical.Kuyimfuneko ukuphanda ngokuqhubekayo kunye nokuphucula inqanaba lemveliso yeemodyuli ze-optical.
Nangona imodyuli ye-optical incinci, indima yayo kwiziko ledatha ayinakuhoywa.Ngokukodwa kwiziko ledatha lanamhlanje apho iimfuno ze-bandwidth ziphakama kwaye ziphezulu, iimodyuli ze-optical zide zithintele uphuhliso lwamaziko edatha kwinqanaba elithile.Ke ngoko, kuyathenjwa ukuba amashishini amaninzi nangaphezulu aya kujoyina imarike yeemodyuli ze-optical ukukhuthaza uphuhliso olukhawulezayo lwemarike yemodyuli ye-optical.Akukho ukugqithisa ukusebenzisa ibinzana elithi "iincinci ezincinci zinefuthe elikhulu" ukuchaza indima yeemodyuli ze-optical kwiziko ledatha.
